To assess problem solving, students are presented a problem to solve or a situation from which they must infer the problem that needs to be solved. Typically, any number of strategies might be used to successfully solve the problem. When scoring student performance where the focus of the assessment is on problem solving, proficiency with particular strategies or other types of procedural (or declarative) knowledge generally is not scored. What is scored are qualities such as the establishment of a clear and appropriate problem representation and sense of goal, the selection of a strategy that is reasonable given the goal to be achieved, and the adequacy with which outcomes from using the selected strategy are evaluated.
